  A method of using the bamboo splitting device 1 according to the embodiment of the present invention will be described. The bamboo splitting device 1 has a function of self-propelled by an engine-driven caterpillar, and can move and operate in a bamboo grove. When the worker feeds the bamboo of various lengths in the longitudinal direction and sandwiches the bamboo between the free rotation roller 13a2 and the free rotation roller 13b2, the roller 15a1 with the protrusion driven by the cylinder 15c and the roller with the protrusion driven by the motors 11a and 11b. By 13b1, the bamboo is pressed against the cutting portion 17 fixed forward and is divided into three equal parts. The divided bamboo is taken out from the discharge unit 19. As described above, since the bamboo is fed at a position immediately before the cutting portion 17 by hydraulic pressure, there is no restriction on the length of the bamboo, and it is necessary to cut the bamboo into a fixed size before the bamboo splitting device 1 is put. It is effective when actually used because it is not available. In addition, since the bamboo trunk to be thrown is pressed from the outside by the protruding rollers 13a1 and 13a2, the center of the bamboo trunk to be thrown is always kept at the center even if the diameter and the outer shape of the bamboo stem change. It can be automatically adjusted to the position of the center of the blade of the split part 17, and the efficiency of the bamboo splitting operation is also improved. Using the bamboo splitting device 1, bamboo cut in a bamboo grove is split on the spot, loaded on a truck, dried, and chip-processed in the factory to greatly improve transport efficiency. Becomes possible. In addition, by dividing the bamboo in the longitudinal direction, drying is the most important step in terms of combustion efficiency when chipping and using it as fuel, but this drying will proceed remarkably.

  The bamboo splitting device 1 may be used in places other than bamboo grove. For example, the bamboo may be used in a factory, or may be used immediately before the felled bamboo is carried into a truck. Further, a belt conveyor or a roller conveyor may be connected to the main body 10 of the bamboo splitting device 1. In this case, the main body 10 may be configured to be vertically movable in accordance with the position of the belt conveyor or the roller conveyor.

  Further, the motors 11a and 11b may operate by air pressure or water pressure, or may operate by electricity. The cylinder 15c may operate by air pressure or water pressure, or an actuator may be used instead of the cylinder 15c. Further, an electric motor may be used instead of the self-propelled engine 103.
